Improved ash-sifter



the inclined sieve D, when the tension of the spring J causes the supplementary side I of the hopper to assume its former position, and close the month of the hopper, when, if the gear-wheel F be revolved by the handle e, the sieve will have a. vibratory shaking mo tion imparted to it, which will cause the coal and cinders that are too large to pass through the sieve to roll o' from the lower end of the sieve and fall into the box O, while the ashes will be shaken through the meshes of the sieve, and fall into the box B, which operation may be repeated until one or both of the boxes B and C are full, when they may be removed from the case A by opening the doors K and L, and, being emptied, they may be replaced, and the doors closed, when the operation may be continued.
